A nurse in the ICU is caring for a client who has heart failure and is receiving a dobutamine drip. The nurse should identify that which of the following findings indicates that the medication is eﬀective?

Increased urine output

Decreased blood glucose level

Decreased blood pressure

Increased heart rate

Answer and Explanation

The Correct Answer is A

Choice A Reason: Dobutamine is a positive inotropic agent that increases the contractility of the heart and improves cardiac output. This leads to increased renal perfusion and urine output, which reduces the ﬂuid overload and edema associated with heart failure. Therefore, this choice is correct.

Choice B Reason: Dobutamine does not have a direct eﬀect on blood glucose level. It may cause hyperglycemia as a side eﬀect, but this is not an indication of its eﬀectiveness. Therefore, this choice is incorrect.

Choice C Reason: Dobutamine may cause a slight decrease in blood pressure due to vasodilation, but this is not its main therapeutic eﬀect. A significant decrease in blood pressure may indicate hypovolemia, hypotension, or shock, which are adverse eﬀects of dobutamine. Therefore, this choice is incorrect.

Choice D Reason: Dobutamine also has a positive chronotropic eﬀect, which means it increases the heart rate. However, this is not a desired outcome for a client with heart failure, as it increases the oxygen demand of the heart and may worsen the condition. Therefore, this choice is incorrect.

Correct Answer is C

Explanation

Choice A: Contacting the provider for further orders is not necessary, because the client has type AB blood, which is compatible with any other blood type. The client can receive type B blood without any adverse reactions.

Choice B: Notifying the blood bank of the discrepancy is not required, because there is no discrepancy. The blood bank sent the correct type of blood for the client, according to their blood type.

Choice C: Administering the blood as ordered is the correct action, because type B blood is compatible with type AB blood. The client will not have any transfusion reactions or complications from receiving this type of blood.

Choice D: Completing an incident report is not appropriate, because there is no incident. The nurse did not make any error or mistake in administering the blood to the client. There is no need to document or report anything unusual.

A. Continuous bubbling in the water-seal chamber B. Occasional bubbling in the water-seal chamber C. Fluctuations in the ﬂuid level in the water-seal chamber D. Constant bubbling in the suction-control chamber

Correct Answer is A

Explanation

Choice A Reason: Continuous bubbling in the water-seal chamber indicates an air leak in the chest tube system, which can compromise the drainage of air and ﬂuid from the pleural space and impair lung expansion.

Choice B Reason: Occasional bubbling in the water-seal chamber is normal and expected, as it indicates that air is being removed from the pleural space.

Choice C Reason: Fluctuations in the ﬂuid level in the water-seal chamber are normal and expected, as they reﬂect changes in intrathoracic pressure during inspiration and expiration.

Choice D Reason: Constant bubbling in the suction-control chamber is normal and expected, as it indicates that suction is being applied to the chest tube system.
